Title: Electron gun structure
Inventor: KURIHARA MASAHIKO
IPC: H01J29/50
Filed: 1993-03-08
Abstract: PURPOSE:To deflect electron beam toward a prescribed direction without increasing the outer diameter of an electrode and the astigmatism in horizontal direction. CONSTITUTION:An electron gun consists of at least a pair of opposite electrodes; a first electrode means to generate electron beam and a second electrode means which is installed coaxially with the first electrode means composing the first electrode and which composes main lens to converges the electron beam. The aperture center 1301 of the electrode in the low potential side of a pair of opposite electrodes 130, 140 composing the second electrode means is set unevenly to one side to the center axis 170 of the electron beam and at the same time the aperture center 1401 of the electrode 140 in the high potential side of the pair of the opposite electrodes is set unevenly to the other side, the reverse side to the electrode in the low potential side, to the center axis 170 of the electron beam. Consequently, since electron beam passes the part out of the initial passing route direction of the scattering lens formed in the inside of the electrode in the high potential side, the unevenness of the astigmatism to the deflecting direction of the center axis of the electrode in the high potential side is suppressed and the astigmatism is lowered.
